Abstract
The utility model discloses a testing tube column of an eccentric pressure meter, which relates to a testing tube column of an oil-water well. The testing tube column is formed by additionally provided with an eccentric pressure meter (2) inside the prior eccentric water distributor (1). The eccentric pressure meter (2) is arranged inside the water distributor (1) through an upper connecting barrel (1-1) and a lower connecting barrel (1-2). The eccentric pressure meter (2) is a storage type electronic pressure meter, and mainly consists of a pressure sensor (2-4), an electronic control, acquisition and storage system and a mechanical card remover. When in use, the eccentric pressure meter is directly arranged in the eccentric water distributor (1) by utilizing a salvage machine, and then the eccentric pressure meter goes into the well following the testing tube column so as to continuously test the change state of pressure between the layers. The utility model has the advantages of accurate and reliable testing result, shortening the construction period and so on in the oil-water well with lower stratum pressure.
Description
Technical field: the utility model relates to a kind of oil-water well and tests the tubing string of scurrying.
Background technology: present conventional packer is tested and is scurried technology, general excessive method of cover or the cover platen press of adopting observed the groove situation of scurrying, this method is applicable to scurries that flux is big, strata pressure is higher, test and scurry a little less oil-water well, scurry or oil-water well that strata pressure is lower for little, use the above-mentioned method of scurrying of testing, its shortcoming is, it is all lower to test the accuracy and the reliability of scurrying structure, test for full well and to scurry, must selection much test and scurry a little, then need be lowered to test for many times and scurry tubing string, its shortcoming is that the site operation cycle is long, and labour intensity is big.
Summary of the invention: in order to solve little scurry or oil-water well that strata pressure is lower is tested the accuracy and the reliability of scurrying the result, shorten construction period, look for finding accurately entirely and scurry groove well section, ground observation and bottomhole pressure survey are combined, propose the present technique solution.The utility model includes eccentric injection mandrel 1, and it also includes eccentricity pressure meter 2, and eccentricity pressure meter 2 is installed in the inside of eccentric injection mandrel 1 by following connecting cylinder 1-2 on the eccentric injection mandrel 1 and last connecting cylinder 1-1.Eccentricity pressure meter 2 is made of fishing head 2-1, disconnecting apparatus 2-2, O RunddichtringO 2-3, pressure sensor 2-4, sealing ring 2-5, circuit board 2-6, socket 2-11, plug 2-12, battery 2-13, battery tube 2-14, back casing 2-15 and middle shell 2-16.End at disconnecting apparatus 2-2 is connecting fishing head 2-1, is connecting the end of middle shell 2-16 at the other end of disconnecting apparatus 2-2, and the front end of back casing 2-15 is connected on the other end of middle shell 2-16.Pressure sensor 2-4, sealing ring 2-5 and circuit board 2-6 are installed in the inside of middle shell 2-16, plug 2-12 is plugged on the socket 2-11, battery tube 2-14 is installed in the cavity of back casing 2-15, battery 2-13 is installed among the battery tube 2-14, O RunddichtringO 2-3 at the outside of middle shell 2-16 suit.The utility model is applicable to scurries or oil well that strata pressure is lower little, tests and scurries the result accurately and reliably, for well adjustment, oilwell water shutoff and other measures provide reliable foundation.
